55 hp YTM?

Friend with 10 acre horse ranch bought

This tractor from a dealer 30 miles away. That taught me a lesson. Dealer support is critical. One of the reasons I bought a Kubota from dealer in town about 6 miles away that has been in business since 1967.

The YTM was having issues with regenerative mode. The PM filter I think it's called had to be cleaned.

Why did it need cleaned?
Is there a snake oil he could add to the fuel to prevent it from happening again?

Or if adding snake oil caused this to happen?

I'm still waiting for the Kubota to regen. Only have 32 hours on it and at 72% on PM. At what % will it go into regen?

A friend of mine bought a 35 HP model about 10 years ago before Tier III and it has been got but I don't know how many hours he has on it. Uses it to haul wood out of woods, cut grass with a 3pt mower and blow snow in the winter. His dealer service has been good.

No snake oil for DPF issues. Indeed, many (most? all?) snake oils cause problems.

When your tractor regens depends mostly upon how it is used. I rarely look at the particulate level display on my L6060 and regeneration is seamless.

No additive will clean the exhaust filter. The worst thing you can do is let them sit and idle or just off idle running around. They need to be run at pto speed and worked to get the exhaust temp up to help burn the filter clear until the regen cycle begins. Continuer idling or low speed use will clog the filter to the point it is unable to clear the filter when regenning, requiring a trip to the dealer for filter cleaning or replacement.

I solved the problem by not buying anything with that junk on it to start with.

What does the dealer do to "clean the filter"

Run it thru a hot parts cleaner?

Semis idle a lot, do they have PM?
During winter he lets his tractor warm up at an idle.
Should he let it warm up or just go to work?
He really doesn't have a need to run engine wide open. So that may be his problem. Why didn't regen take care of itself?

The only time I run at 2400 is when mowing. I use throttle advance when operating loader.

Thanks for the education. I'm not too old to learn new things. Only problem I see is remembering the new things. Can't find my memory pills. Are they purple?

I'd start with reading the manual and watching any instruction videos from the manufacturer/dealer.

If it's like a highway truck, there should be a dash switch to run a "Forced Regeneration ".

No solvent.

Some DPFs can be disassembled for cleaning.

Some can be cleaned (sometimes) by so-called "parked" (forced) regen.

Some must be replaced ($$$).

Putting around operation and idling has never been good for any diesel at any time. tier IV emissions just make it worse
.
Diesels by design need to operate at full rpm at full temperature and at full power for hours or days at a time.
One of the reasons why spark ignition engines are used in construction etc on generators , pumps , Man lifts , fork lifts etc. A spark ignition engine is more tolerant of putting around and idling.

I heard that " Bad Boy Zero Turn mowers are now a TYM tractor distributer .

I would think you are getting close to a regen, working it longer times and at higher RPM's should increase the interval, putting around plugs them up.

Do not let a modern diesel idle,if you open a gate shut it off, open the gate and drive through. I am 11 years driving these things. My new one has a 3 Minuit idle timer on it,I never want it to shut it down,it has, but not very often. The local dealer and the lease company both replace the exhaust filters(reman)not clean them.

I retired (truck mechanic)a few yrs after the diesel after treatment came out. But what I was taught is the earlier versions with particulate filter only, made more soot(particulate), but less nitrous oxides(NOX), which is a big concern with air pollution. This has to do with injection timing and EGR valve timing. The next system has the particulate filter and another chamber where the Diesel Exhaust Fluid is injected. No more muffler. With the DEF system there is more nitrous oxide, but less soot. The DEF reduces the NOX. Timing is changed. With DEF the system requires less regenerations. The particulate filter collects the soot, and has sensors to measure input and output pressure difference, and temp sensors. When the restriction is too high, some engines inject fuel up stream of the filter, others richen the fuel to the injectors, and this raises the exhaust temp and causes the soot to burn off the face of the catalyst face inside the particulate filter. This turns the soot into ash and deposits it in another section of the filter. This ash has to be removed periodically. This is called regen. How often regens are required all depends on how the engine is used. Hotter exhaust from hard work is the best thing. Idling is bad for the system. Hot and cold weather plays a factor too. During a regen the exhaust gets extremely hot.
Semis no longer idle all night-they have small engines behind the cab to run its own a/c and heater system. Ecms are programed to shut the engines off after a timed limit when idling.
Cleaning the particulate filter is done by replacing with a factory reman. Some are made a solid unit and others are made sectional. Mark.

Actually , leave the engine at 3/4 s of PTO rpm instead of shutting it off while opening a gate or taking a whiz. Shutdown just cools everything off .

That?s the smart thing to do because sooner or later it leads to heart ache and a weak checking account

I am impressed that so many guys know now that diesels should not be idled. My Peterbilt has a a high idle switch that I switch on virtually any time that I am getting out but leaving it running. In two years, to the best of my knowledge, it has never regenerated. WRT dealer support, I have had various tractors of five different brands over 34 years, and I am still trying to figure out this need fo a nearby dealer thing. Why?

David and several others are correct. Don't putt these engines. the harder they work the better. I was afterhours dispatch for a large trucking company. Driver called in that his engine would not regen and needed a dealer. I told him the closest dealer was about 200 miles away and 3 days before he could be serviced. I suggested that we try something different, driver put his 10 speed transmission in 9th and ran it against the governor. He called 1/2 an hour later said all kinds of black smoke and sparks coming from the stack. I checked on him 2 hours later he was back in 10th gear. His regen light would not go off but truck ran fine. A week later we got him into a shop for repair Just my two cents

People around me with these newer tractors spend more on them than I ever do on my older ones.They pay more to hook up to the computer analyzer to find the problem than fixing most problems cost me.And I can let mine idle for a few minutes without fouling anything up.

Me too. In ~30 years I've had my old tractor, I've needed parts from the dealer/factory twice. First time went to the dealer about 30 miles away to order and pick up. Second time ordered on the web and had shipped to my door.

I agree I wouldn?t have one especially with that emissions and computer crap

Friend of mine has a ?new?Chevy pickup he spent three grand on it last winter on emissions repair

That TYM tractor should have automatic regen, the exhaust temp light will be on during auto regen. If you don't allow it to auto regen, then you need to consider doinf it manually, maybe at the end of the day or during a break.

If the tractor needs to regen, both the regen and engine warning lamp will be on, then you can regen manually. Set parking brake, idle engine and you will see the ACK lamp blink, press and hold ACK button for 3 secs, RPM will increase to 2200, ACK and Exh temp lights will come on and then go out when regen is complete (about 30min).

Operating the engine around 2000-2200 rpm should allow the DPF to heat up and allow auto regen. If the exh temp light is on, then try to keep operating the tractor in the above conditions until the light goes off.
